BioShock creator Kevin Levine spoke today at GDC08, and stated that gamers don't actually care about storylines in their videogames.
"The bad news for storytellers is that nobody cares about your stupid story," Levine said. "Nobody cares about the thing you've been writing in your math notebook since you were in 11th grade about the dark lord Lagon and the fifth period of the Elven uprising, and all that crap you've been working on forever. I know that's hard to hear because you care about it a lot, but the audience is not your mom; they have no reason to be predisposed positively to the things you've been thinking about, no matter how detailed or lovingly you crafted it."
